ᐅ Installing awnings in a "challenging" mounting situation

I hope I have chosen the right subforum, as my question doesn’t perfectly fit anywhere.

We are planning to install one or two awnings above our terrace. It is a multi-family building, and we have a ground-floor apartment with a continuous terrace area, as wide as our living space (see pictures). Above part of it is the balcony of the apartment above (width approximately 4m (13 feet); the awning would be about 3.5m (11.5 feet) wide and 3–3.5m (10–11.5 feet) deep), while the other area is uncovered (width about 5m (16.5 feet); the awning would be 4.5m (15 feet) wide and 3.5–4m (11.5–13 feet) deep). Since our terrace faces roughly south-southwest, we would ideally like to have an awning over both areas, as the balcony offers only little sun protection during the day. However, the uncovered area is more important. So far, we have obtained quotes from local specialist companies. They also examined the situation on site, as the installation is somewhat complicated (as it turned out later). These companies should know what they are doing, but so far we have not felt completely confident about any of the proposed solutions or fully convinced. Therefore, we would appreciate additional opinions about the possible installation methods.

Uncovered terrace area:

The “installation issue” with the uncovered terrace area is that the first-floor apartment has floor-to-ceiling windows spanning the entire width (see pictures as well). These floor-to-ceiling windows naturally have fall protection barriers. Because of these barriers, the awning cannot be attached directly to the wall.

One company (which installs Klaiber awnings) suggested mounting the awning directly onto the brackets/supports of the fall protection barriers on the floor-to-ceiling windows. What do you think about this? I have a feeling these supports are probably not designed to also carry the weight of an awning!? We were told to ask the construction company about this, but there is no cooperation or assistance available. Additionally, the awning would be quite large at 4.5m x 4m (approximately 14.75 ft x 13 ft) (fully extended 18m² (194 ft²)). That must be a considerable weight.

Another company (which installs Hella awnings) proposed having custom spacer brackets fabricated by a metalworker and then attaching the awning to the wall. I actually prefer this option, but custom-made brackets? Are there no ready-made solutions from the awning manufacturers that are approved for this? Also, there is the question regarding the external thermal insulation composite system (ETICS, or “external wall insulation”). These custom spacer brackets would be attached to the wall, but the insulation is not load-bearing material. Can it handle these loads at all? The company said that nowadays you can’t remove the ETICS, but there are special anchor bolts for this. I looked it up, and such anchors do exist, but wouldn’t these brackets need to be fastened directly to the concrete behind the insulation? Presumably, just like the fall protection brackets, which come out of the wall, I assume this is how it should be done. Otherwise, the screws would have to go from the anchor in the concrete through the insulation before holding the spacer brackets. This would create quite a lever effect because the insulation is quite thick nowadays, and the screws have no grip in it. It would feel like hanging a heavy object 15–20cm (6–8 inches) away from the wall, only supported by screws. Or am I misunderstanding something?

As a layperson, I would suspect the best option is to remove some of the insulation, then fasten the spacer brackets underneath the insulation directly to the concrete, and then close the insulation again. After that, mount the awning on these spacer brackets.

Covered area:

There is no problem with the insulation here, but the same issue regarding the distance applies. Here, it is the fall protection of the balcony instead of the windows, as unfortunately it is a prefabricated balcony and not a “built-on” balcony. Basically, the question is where and how it should be best attached here. Also with custom spacer brackets?

I would greatly appreciate expert advice. I am also open to tips regarding awning manufacturers (How do Klaiber and Hella compare?). I often see Markilux, Weinor, and Warema described as top brands. I have read less about Hella and Klaiber so far.

Our sail does not have sensors but is electrically powered with remote control. The maximum extension is 4.8m (16 feet), and the larger the sail, the less the person has to move to stay in the shade.

Hello Nida, could you share some information about the manufacturer of your sail, possibly also the costs and maybe one or two photos?
We are also looking.
Thank you very much.

I think that looks good for you. We were considering an awning so that no additional support posts would be needed... otherwise, it ends up looking like a collection of different supports (balcony, awning...). My idea now was possibly to use the balcony post for a glass canopy with a retractable awning/shade underneath on guide rails. That way, only one additional support post would be needed on the far right. But then you have to consider if that really makes that much of a difference... otherwise, the roof would need to extend significantly further out. Or you could try to make it somewhat continuous, meaning what I just described but also extending the balcony as a roof with shading underneath. However, I suspect that would be extremely expensive. The two quotes for two awnings each (uncovered area and balcony) are already around 7000-8000€ (7,700-8,800 USD).

Our alternative was the Weinor Plaza Viva Pergola Awning,
also not too bulky. Just take a stroll through sunshade exhibitions,
with your photos on your phone.

What is the approximate price including installation, etc.? What size?

Same price range, but there would have been two awnings with a center rail.
